[Niddah 10a:1](https://torahapp.org/share/book/Niddah/r/10a:1)

הֲדַר קָחָזְיָא בְּעוֹנוֹת, מַאי? אָמַר רַב גִּידֵּל אָמַר רַב: פַּעַם רִאשׁוֹנָה וּשְׁנִיָּה — דַּיָּהּ שְׁעָתָהּ, שְׁלִישִׁית — מְטַמְּאָה מֵעֵת לְעֵת וּמִפְּקִידָה לִפְקִידָה.

**William Davidson Edition - English:**
The Gemara asks: **What** is the *halakha* if she **then sees** menstrual blood **at** regular intervals of thirty-day **cycles?** Is her time sufficient, or does she transmit impurity retroactively? **Rav Giddel says** that **Rav says:** With regard to the **first time and** the **second** time that she sees menstrual blood, **her time is sufficient.** After the **third** time, **she transmits impurity** retroactively **for** a twenty-four-hour **period or from examination to examination.**


###### Niddah 10a:2
[Niddah 10a:2](https://torahapp.org/share/book/Niddah/r/10a:2)

וְעוֹד עָבְרוּ עָלֶיהָ שָׁלֹשׁ עוֹנוֹת, וְרָאֲתָה — דַּיָּהּ שְׁעָתָהּ. הֲדַר קָחָזְיָא בְּעוֹנוֹת, מַאי?

**William Davidson Edition - English:**
The *baraita* further teaches, with regard to a young girl who did not experience bleeding for three typical cycles and then saw blood, **and three further** expected menstrual **cycles passed** without her experiencing bleeding **and** then afterward **she saw** menstrual **blood,** that **her time is sufficient.** The Gemara asks: **What** is the *halakha* if she **then sees** menstrual blood **at** regular intervals of thirty-day **cycles?**


###### Niddah 10a:3
[Niddah 10a:3](https://torahapp.org/share/book/Niddah/r/10a:3)

אָמַר רַב כָּהֲנָא, אָמַר רַב גִּידֵּל, אָמַר רַב: פַּעַם רִאשׁוֹנָה — דַּיָּהּ שְׁעָתָהּ, שְׁנִיָּה — מְטַמְּאָה מֵעֵת לְעֵת וּמִפְּקִידָה לִפְקִידָה.

**William Davidson Edition - English:**
The Gemara answers: **Rav Kahana says** that **Rav Giddel says** that **Rav says:** The **first time** that she sees menstrual blood, **her time is sufficient.** After the **second** time, **she transmits impurity** retroactively **for** a twenty-four-hour **period or from examination to examination.**


###### Niddah 10a:4
[Niddah 10a:4](https://torahapp.org/share/book/Niddah/r/10a:4)

מַנִּי? רַבִּי הִיא, דְּאָמַר: בִּתְרֵי זִימְנֵי הָוֵי חֲזָקָה.

**William Davidson Edition - English:**
The Gemara asks: **Who is** the *tanna* of the *baraita*? The Gemara answers: Since the *baraita* teaches that she attains the status of a regular adult woman upon the third sighting of menstrual blood, apparently it is **Rabbi** Yehuda HaNasi, **who said** that **presumption is** established **by two occasions.**


###### Niddah 10a:5
[Niddah 10a:5](https://torahapp.org/share/book/Niddah/r/10a:5)

אֵימָא סֵיפָא: עָבְרוּ עָלֶיהָ שָׁלֹשׁ עוֹנוֹת וְרָאֲתָה — דַּיָּהּ שְׁעָתָהּ, אֲתָאן לְרַבִּי אֱלִיעֶזֶר!

**William Davidson Edition - English:**
The Gemara raises a difficulty: **Say the latter clause:** If she then **passed three** expected menstrual **cycles** without experiencing bleeding, **and** then **she saw** menstrual blood, she returns to the status of a young girl and **her time is sufficient.** In this ruling **we come to the opinion of Rabbi Eliezer,** who holds that any woman who passed three expected menstrual cycles without experiencing bleeding is presumed not to be menstruating and her time is sufficient. Is the *baraita* in accordance with the opinion of Rabbi Yehuda HaNasi or Rabbi Eliezer?


###### Niddah 10a:6
[Niddah 10a:6](https://torahapp.org/share/book/Niddah/r/10a:6)

וְכִי תֵימָא רַבִּי הִיא, וּבְעוֹנוֹת סָבַר לַהּ כְּרַבִּי אֱלִיעֶזֶר, וּמִי סָבַר לַהּ? וְהָא לְאַחַר שֶׁנִּזְכַּר קָאָמַר! אֶלָּא רַבִּי אֱלִיעֶזֶר הִיא, וּבִוְסָתוֹת סָבַר לַהּ כְּרַבִּי.

**William Davidson Edition - English:**
**And if you would say** that the *tanna* of the *baraita* **is Rabbi** Yehuda HaNasi, **and in** the case of a woman who passes three menstrual **cycles** without experiencing bleeding, he **holds in accordance with** the opinion of **Rabbi Eliezer, but does he** really **hold** in accordance with **this** opinion? Doesn’t the *baraita* **state** that **after** Rabbi Yehuda HaNasi **remembered** that several authorities disagreed with the ruling of Rabbi Eliezer, he said: Rabbi Eliezer is worthy to rely upon in exigent circumstances, i.e., only in exigent circumstances. The Gemara concludes: **Rather,** the *tanna* of the *baraita* **is Rabbi Eliezer, and with regard to** menstrual **cycles** he **holds in accordance with** the opinion of **Rabbi Yehuda HaNasi,** that a presumptive cycle is established after two occasions of seeing menstrual blood.


###### Niddah 10a:7
[Niddah 10a:7](https://torahapp.org/share/book/Niddah/r/10a:7)

כֶּתֶם שֶׁבֵּין רִאשׁוֹנָה וּשְׁנִיָּה — טָהוֹר, שֶׁבֵּין שְׁנִיָּה וּשְׁלִישִׁית — חִזְקִיָּה אָמַר: טָמֵא, רַבִּי יוֹחָנָן אָמַר: טָהוֹר. חִזְקִיָּה אָמַר: טָמֵא, כֵּיוָן דְּאִילּוּ חָזְיָא מְטַמְּאָה — כִּתְמַהּ נָמֵי טָמֵא, וְרַבִּי יוֹחָנָן אָמַר: טָהוֹר, כֵּיוָן דְּלָא אִתַּחְזַקָה בְּדָם — כִּתְמַהּ נָמֵי לָא מְטַמֵּינַן לַהּ.

**William Davidson Edition - English:**
§ With regard to a young girl who was just starting to menstruate, the Gemara states: If she finds a blood **stain between** the **first** and **second** time that she sees menstrual blood, she is **pure.** If it is **between** the **second and** the **third** time, **Ḥizkiyya says:** She is **impure; Rabbi Yoḥanan says:** She is **pure.** The Gemara explains the reasoning behind their respective opinions. **Ḥizkiyya says:** She is **impure, since if she had seen** menstrual blood it would **render her impure.** Consequently, her blood **stain is also impure. And Rabbi Yoḥanan says:** She is **pure, since she has not** yet attained the **presumptive status of** one who sees menstrual **blood.** Therefore, **we also do not render her impure** on account of **her** blood **stain.**
